Benefits of technology

[0009]As shown in FIG. 3 and FIG. 4, the present invention is composed of press buttons which are pervious to light, a press button circuit board which is pervious to light, a control circuit board, and a light guiding board, wherein the control circuit board is provided with a control circuit for dynamically cont

Problems solved by technology

As shown in FIG. 1, a plurality of light emitting diodes C (with characteristics of long lifetime and ease of driving) are installed on a control circuit board B. Light will directly penetrate out after pasting press buttons A with the control circuit board B. However, a plurality of point light sources are constructed when the plurality of light emitting diodes emit light simultaneously, which will not be able to easily cause a uniform brightness.
If more light emitting diodes C are added to increase the brightness, power consumption will also be increased.
Referring to FIG. 2, a luminescence board D (with characteristics of short lifetime, light in weight and thin, and hard to drive) is installed between press buttons A and a control circuit board B. Light will penetrate out after pasting the press buttons A with the luminescence board D. However, for the existing luminescence board D, its brightness is low and power consumption is high, and an extra driving circuit D1 should be installed for using the luminescence board D. Furthermore, a noise will be generated when the luminescence board D is emitting light.

Embodiment Construction

[0025]Referring to FIG. 5, FIG. 6, and FIG. 7, a light guiding board F, a press button circuit board A1 which is pervious to light, and press buttons A which are pervious to light, are installed and overlaid in sequence on a control circuit board B inside a remote controller H, a keyboard I, and a telephone set J. When light G enters the light guiding board F from light emitters E, is uniformly distributed in an interior of the light guiding board F, and penetrates out from the light-pervious press button circuit board A1 and press buttons A, a control circuit B1 is controlling the light emitters E to emit light.

[0026]The light-pervious press buttons A and press button circuit board A1 are made of light-pervious material, and the light G emitted from the press buttons A has a high and uniform brightness.

[0027]Referring to FIG. 3 and FIG. 8, the light emitters E can be installed on the control circuit board B, or an independent light emitter E1 can be used. The light emitters E, E1 a...

Abstract

A press button light emitting structure consists of a light-pervious press button circuit board and a light guiding board installed underneath light-pervious press buttons, wherein peripheries of the light guiding board are pasted with light emitters. Light can be uniformly distributed and transmitted in an interior of the light guiding board, and penetrate out from the light-pervious press button circuit board and press buttons, when the light emitters emit light. The light penetrated out has a good brightness and uniformity. In addition, a control circuit is used to dynamically control lighting display, such as an on / off, brightness, and color, to the light emitters.

Description

BACKGROUND OF THE INVENTION[0001](a) Field of the Invention[0002]The present invention relates to a press button light emitting structure, and more particularly to a light emitting structure wherein a press button circuit board which is pervious to light and a light guiding board are installed underneath the press buttons respectively, and the peripheries of light guiding board are pasted with light emitters, such that light can be uniformly distributed and transmitted in an interior of the light guiding board and penetrate out from the press button circuit board which is pervious to light and the press buttons when the light emitters emit light. The light penetrated out has a good brightness and uniformity.[0003]When the light enters the light guiding board from the light emitters, is uniformly distributed in the interior of the light guiding board, and penetrates out from the press button circuit board which is pervious to light and the press buttons, a control circuit is controll...
